The core library, all my presets, the Live 8 user library, everything.

I had a moment of panic today when this happened to me with 9.0.2. Then I realized that I had inadvertently typed something into the browser search field.

It was one of those cases where I thought I had switched to a different program and just started typing, realized I wasn't in the program I thought I was in and switched. When I switched back to Live, the browser content pane was empty; it looked like everything was gone. After a few minutes of poking around, I noticed some text in the search field. When I cleared the field, everything came back.

Not saying that's what happened to you, but because the search happens automatically as you type, it's easy to overlook.

Especially because the browser is still a bit flakey at times and seems to lag behind every now and then. So in situations like these the first thing to do is check the physical location of your setup. I'd really recommend writing those locations down or memorizing them (for example; my stuff sits in both d:\ableton as well as c:\users\<me>\documents\ableton). So if you see something odd in Live; check the physical location first!

But in all honesty; I've seen a lot off stuff happening in Live, and a lot of that inflicted by myself (think bizarre M4l experiments). Even so I've never seen Live actually disrupting physical data. Maybe this is tempting fate here; but so far the only thing where data corruption sometimes occurred was with Livesets.

well turns out there was a word in the browser which prevented ANYTHING from coming up but that particular word/item/ scared the hell outa me.

Maybe they should put something like "No search results" in the content pane to remind you why it's empty. Then again, once you've had a moment or two of panic, forgotten text in the search field will be the first thing you'll look for from then on.
